OBS-Studio: Stage is transparent under Wayland (sway)

colemickens commented 5 years ago

Issue description

When using OBS-Studio with Wayland, the stage is transparent instead of visible. This makes using OBS highly impractical. It can be worked around by launching with env QT_QPA_PLATFORM=xcb obs

Steps to reproduce

Make sure you're using Wayland. (It's possible this only repros under Sway.
Make sure qt5.qtwayland is available in your (system) environment.
Open OBS-Studio with the QT Wayland backend.
Observe the other windows or background shining through.

output

Technical details

Please run nix-shell -p nix-info --run "nix-info -m" and paste the results.

Amusingly, it does still work: https://photos.app.goo.gl/HbpKGF7uaHasQ88y5

I'm having a heck of a time figuring out what's going on, might just be Qt being weird? Depending on what scale output is, if I have restarted Sway recently, OBS behaves differently and oddly.

For example, right now, I'm opening it with env QT_QPA_PLATFORM=wayland obs and it says as much in the log, yet it's clearly opening in Xwayland and crashes if I call pkill Xwayland. Bizarre.

https://github.com/obsproject/obs-studio/pull/2097 might fix it.

I am encountering the same problem on Fedora 32. When starting obs in the command line i get this output:
